Embodiment Construction

[0032] Technical scheme of the present invention is as follows:

[0033] A passenger flow counting device based on infrared photoelectric technology includes an infrared transmitter, an infrared receiver, a microprocessor, a clock, a memory and a data output module. in:

[0034] an infrared emitter for emitting an infrared beam;

[0035] The infrared receiver is used to receive infrared rays, and the two infrared receivers respectively receive the infrared rays emitted by the infrared transmitter to form two infrared rays;

[0036] Microprocessor for processing time signal and infrared signal;

[0037] Clock, this device adopts 11.0592MHz clock, uses the clock to generate 2ms time base, that is, collects the blocking situation of the infrared receiver every 2ms.

[0038] memory, used to store the calculation results of the microprocessor;

[0039] The data output module is used to output data results;

[0040] The passenger flow counting device of the infrared photoelectr...

Abstract

The invention relates to a passenger flow counting device based on infrared photoelectric technology, wherein the passenger flow counting device is capable of excluding objects. When the distance between a front object and a rear object is longer than or equal to 1 centimeter, the objects can be recognized. The passenger flow counting device comprises infrared transmitters, two infrared receivers, a microprocessor, a clock, a storage and a data output module, the two infrared receivers receive infrared rays transmitted by the infrared transmitters respectively to form two infrared rays, the infrared rays are blocked up when people or the objects pass the space among the transmitters and the receivers, the movement direction, the movement speed and the widths of the objects and the distance between the objects are calculated by judging the blocking time sequence of the infrared rays, counting is not performed when the widths of the objects are smaller than a preset width value, the count is 1 when the widths of the objects are larger than the preset width value and no distance is reserved between the objects, and the count is 2 when the widths of the objects are larger than the preset width value and the distance is reserved between the objects. Precision, sensitivity and response speed of an infrared counter can be effectively improved, and the passenger flow counting device is applicable to counting other non-transparent objects.

Description

technical field [0001] The invention belongs to the technical field of automatic detection, and in particular relates to a passenger flow statistics device based on infrared photoelectric technology. Background technique [0002] The number of customers is directly related to the operating performance of the retail industry, and it is one of the most concerned operating indicators in the retail industry. As an important tool for retail market research, almost all foreign shopping centers, shopping malls, large supermarkets and chain outlets are conducting long-term customer flow statistics and trend analysis. With the intensification of competition in the retail industry, the business model has gradually changed from traditional extensive operation to refined management, and the analysis of daily passenger flow characteristics is particularly important. At present, many domestic operators have realized the importance of passenger flow data for analysis and decision-making, ...
